On behalf of the team, I’m delighted to announce the availability of the third Spring Data 2021.1.0 milestone. This release is the last milestone before entering the RC phase on mid October. This release ships besides numerous bugfixes and dependency upgrades a series of notable enhancements:


  • Support jMolecules’ @Identity as ID annotation
  • Publish delete events by repository methods deleteInBatch and deleteAllInBatch methods


  • Support for MongoDB 5.0 aggregation stages and operators including $setWindowFields for aggregations using time-series.
  • Configuration options for MongoDB’s versioned Server API.
  • Schema derivation for encrypted fields.


  • Options to reuse bound connections.
  • Enable ReactiveRedisTemplate for multi-tenancy usage.
  • Performance optimizations using Jedis with Redis Cluster.


  • Improved client configuration callbacks.


  • Support for cyclic mapping in projections.

We are working towards a release candidate release in mid-October and a GA release in early November. Watch out for the upcoming Spring Boot 2.6.0-M3 release in the next few days that is going to pick up this Spring Data milestone.
